Many network storage engineers simply don't understand bandwidth (or the

per second and storage and networking architects simply see 10Gbe and
assume that's good enough. A 10Gbe connection can do about 1.4GB/s..
100Gbe can do 12.5GB/s. To the wrong engineer you can explain this
until you're blue in the face and they won't get it. You need to divide
Gbe by 8 to get about the GB/s throughput. Explain to them that a USB-C
interface is capable of 10Gbe... So you're throttling millions of
dollars in technology to the speed of a consumer grade USB-C interface.
When infact an ESS can drive at least 2x100Gbe to saturation.
I don't have an ESS but a classic SAN array and Spectrum Scale and I can
saturate 32*8Gbe fiber connections.
Your kidding right? That's basic competency for the job!!!
